Large Herbivores Essential To Spread Soil Nutrients

Despite the quirks, there are two important insights to this study. First, today we are rapidly losing our few remaining large animals (forest elephants have decreased by 60% in the last 10 years alone). Losing these animals will critically impair our future ecosystems as we lose their nutrient distribution capacity. Next there is an observed ecological rule called Cope’s rule that has shown that animals tend to get bigger over time. Basically, it is a good evolutionary strategy to get big because then it is harder for predators to eat you. Combining this rule, with what I have found in this study, that large animals are disproportionately important for the distribution of nutrients, indicates that the planet may have an intrinsic mechanism of increasing fertility over time.
